摘要： Implementations of the present disclosure relate to an apparatus and a method for reducing a selenium-content of a fluid-input stream. The present disclosure includes components and steps for performing chemical modifications of a fluid-input stream and further components and steps for performing physical modifications of a chemically-manipulated fluid stream. When the fluid-input stream has a selenium content the chemical modification of the fluid-input stream drives at least a portion of the selenium content into a selenium-containing solids phase. The chemical modifications include at least oxidation, coagulation, chelation and flocculation. The present disclosure also includes components and steps for performing physical modifications that separate and remove some or all of the selenium-containing solids phase from the liquid phase, which reduces the selenium content of the liquid phase.

摘要： There is described an on-line device for controlling a fluid treatment process configured to inactivate a microorganism in a flow of fluid using ultraviolet radiation and a chemical disinfectant. The device includes: a memory for receiving a calculated database of dose response for the ultraviolet radiation and for the chemical disinfectant for a fluid treatment parameter; means to obtain input data about the fluid treatment parameter from the process; means to compare the input data with calculated database; and means to adjust one or more of the amount ultraviolet radiation and the chemical disinfectant added to the flow fluid in response to a difference between the input data and calculated database. There is also described a process for controlling a fluid treatment process configured to inactivate a microorganism in a flow of fluid using ultraviolet radiation and a chemical disinfectant.
